Application June 25, 1956, Serial No. 593,703

14 Claims. (Cl. 88-16) My present invention is a continuation in part of my Patent No. 2,813,452 issued November 19, 1957 and relates particularly to apparatus for distributing odors in timed sequence with respect to a motion picture film.

Essentially my present invention contemplates the arrangement of a plurality of containers or cells, each containing a particular odor and connected in sequence with each other to form a movable train of containers or cells which may be wound spirally on a reel. The sequence of odors in the containers is predetermined in accordance with the sequence of views or scenes in the motion picture to be shown. One end of the train of cells or containers is connected by an appropriate band or other connector to a take-up reel and the train of cells or containers is thereafter moved in a step by step fashion pursuant to signals either placed on the motion picture film and picked off therefrom, or generated in any appropriate fashion, synchronized with the film.

The movement of the train of cells from one step to the next is then followed by an appropriate cycle of withdrawal of the odor or smell from the cell or container and emission thereof into the area in which the viewers of the motion picture sit.

On completion of the viewing cycle, the train of cells may be rewound from the take-up reel to the supply reel. Thus, each film or group of reels constituting a complete motion picture may be accompanied by a supply reel containing a train of cells spirally wound thereon with the odors in the cells or containers in appropriate sequence.

The primary object of my invention, therefore, is the provision of means for emitting odors in timed sequence with respect to a motion picture film.

Another object of my invention is the arrangement of perfumes or odors in a plurality of cells or containers coupled into a train sequence, the containers being wound on a supply reel and being unwound in sequence corresponding to the sequence of the scenes with respect to which the odors are to be emitted.

Essentially, my invention, since it is a continuation in part of the above-mentioned application, is based on the principles thereof, but is drawn to specific apparatus which, after substantial experiment, has been found to be effective and operative to produce appropriate timed emissions of odor in sequence with particular film scenes in a viewing area approximately one hundred feet long by forty-five feet wide and having a ceiling approximately forty feet high.

The theory of emission of odors in sequence with scenes which are projected has already been covered in the aforementioned application. The present. invention relates to specific apparatus which has been found practical and useful in connection with the showing of motion pictures in auditoriums.

The foregoing and many other objects of my invention will become apparent from the following description and drawings in which:

Figure 1 is an expanded schematic view showing the components and method of operation of my invention.

Figure 4 is an enlarged view in perspective of a portion of the odor distributing apparatus which is seen in Figure 1.

Figure 5 is an enlarged vertical cross-sectional detailed view of a portion of the odor distributing apparatus seen in Figure 1.

Referring first to Figure 1, my novel odor selecting and emitting device comprises a supply reel 10 on which a train 11 of odor containing cells 12, 12 is spirally wound. The supply reel 10 is so arranged that it may be removably engaged and keyed to shaft 13, which shaft is free to rotate to permit the supply reel 10 to rotate in response to any force tending to unwind the train 11 of cells or container 12 from the supply reel 10.

While the shaft 13 is free to rotate, it is nevertheless connected to a rewind motor 14 which may be energized t0 rewind the supply reel 10 and thus wind up the train 11 of cells 12 in spiral fashion upon the supply reel 10. That is, when the operation of the sequence is completed and the train 11 of cells 12 is completely unwound from:

the supply reel 10, then an appropriate circuit may be closed .in a manner which is obvious to energize the motor 14 to rewind the supply reel 10, thereby rewinding the train 11 of cells 12 into a complete spiral on the supply reel 10 and preparing the supply reel 10 for the next showing of the film in connection with which the odors are to be emitted.

In order that the cells 12 may be interconnected to form a train which may be spirally wound and unwound from the supply reel 10, each of the cells 12 as seen in Figure 1, Figure 2 and Figure 3, is provided at its trailing end with a lug 15 to which is secured a downwardly directed pin 16. The forward or leading edge of each cell 12 is provided with another lug or bracket 17 in a horizontal portion 13 of which is provided an open ing to receive the downwardly directed pin 16. Thus, each of the cells 12 is provided with a coupling to the next cell comprising the downwardly directed pin 16 at the trailing edge of each cell and the opening in the hori' zontal member 18 at the leading edge of each cell. This type of coupling provides for lateral flexibility of the train 11 and thereby, since sufiicient clearance is provided between the leading and trailing edges of adjacent cells, permits the cells to be spirally wound on the supply reel 10 or the tal e-up reel hereinafter described. The leading cell is provided at its leading edge with a hasp 19 to which a belt 20 is secured, the said belt being detachably engaged with a portion of the hub 21 of the take-up reel 22. The take-up reel 22 is also removably keyed to a shaft 23.

Essentially, my novel device is designed to move the train 11 of cells 12 in a step by step fashion in timed sequence so that the train 11 is unwound from the sup ply reel 10 and wound up on the take-up reel 22.

For this purpose, appropriate tensioning means is provided between supply reel 10 and take-up reel 22, or rather between their respective shafts 13 and 23 in order to hold the train 11 of cells 12 appropriately taut and in such condition that the movement of the train 11 of cells 12 by other means hereinafter described will be exactly in response to the energization of such other means, without any coasting of the train 11 of cells 12 after the drive or moving members cease operation so that each of the cells 12 of the train 11 will be appropriately positioned in the manner hereinafter described.

In the embodiment shown, the tensioning means com Patented Sept. 22, 1959 prises a plurality of weights 25 riding in guide 26 and secured to cable 27 which rides over the guide pulley 28 and is wound up on reel 29 mounted at the lower end of shaft .23. The weights 25 acting through the cable 27 on reel 29 tend to 'otate the shaft 23 and the supply reel 22 in a direction in which it will wind up the train 11 of cells 12 and hence draw the train 1.1 towards the fight With respect to Figure l.

Shaft 13 of supply reel 10 may, if dfesired, be appropriately tensioned oppositely, although appropriate friction means Whieh take into account the sliding friction of the cells 12 may also be utilized so that in the absence of the additional drive for the cells hereinafter described, the entire train 11 of Cells 12 and the supply reel 10 together with the take-up reel 22 will "remain stationary. In addition, an appropriate indication of the position of the train 11 of cells 12 showing the particular cell or cells in position to be acted on by the apparatus hereinafter described is provided by the additional weight 30 connected by cable 31 to reel 32 on shaft 23, the said weight 30 riding in the guide 33 having a slot 34. The slot 34 of the guide 33 is preferably arranged to be visible at the front of the housing of the machine and the position of the weight 30 in the slot will provide an indication of the number of cells that have been withdrawn from the supply reel 10 to the position to be acted on by the apparatus hereinafter described.

The device may be arranged for operation in accordance with appropriate signals. At the lower left hand section of Figure l, I have shown very generally one method of signalling which may be used. The motion picture film 40 which is moved by known projection operating apparatus over the sprockets 41, 42 past the image projecting light source 43 is also moved past the light source 45 registering with an appropriate margin of the film which carries appropriate markingsrwhich furnish signals in the form of interruptions of various kinds of the beam from the light source 45. A signal responsive device 46 which may be photosensitive or may be operative in any desired manner (including an electromagnetic pick up which would therefore not require a light source) will pick up the signal from the film 40. The signal that is picked up by the signal responsive device 46 is then past to the amplifier 47 where it is appropriately amplified.

From the amplifier 47, the signal is then impressed upon a sequence selecting device 48 which may be of the general type described in my above mentioned application or it may comprise a plurality of switches operated in timed sequence to perform the various operations hereinafter described in the appropriate sequence. This sequence of operations may be grouped as:

(1) Movement of the train of cells to a next position;

(2) Operation of a connecting member to engage the cell or cells at the operating position and connect the interior of the cells to the odor emitting device;

'(3) Operation of local pumps in the device and remote pumps and fans external of the device for removing a portion of the odor or gas from the cells and emitting it into the area occupied by the viewers of the film;

(4) Removal of the connecting device from the cells and simultaneously closing of the cells;

Continued operation and then cessation of the operation of pumps and fans in order to remove the last trace of odor and emit it into the room where the viewing operation is taking place.

This sequence may be performed by a rotating switch of the type described in my last mentioned application or a plurality of automatically timed switches, one for each individual operation, each of the switches being of the type which is automatically reset to zero on completion of its operation and being of the type which will on receipt of an appropriate signal close the circuit after a desired time interval and opening a circuit after a desired time interval.

Thus the sequence selecting device 48 may be a single opera-ting switch with a plurality of separate contacts engaged during a cycle of operation or it may be a plurality of switches simultaneously operated but individually set for this timed sequence through a cycle. This assembly is indicated by the sequence selector device 48 which is shown; the individual sequence selectors or circuits therefrom are therefore connected by lead 50 to operating motor 51; by lead 52 to the operating coils of the selecting device 53; by lead 54 to the local blowers 5'5, 55; by lead 57 to the local diaphragm pumps 58; by lead 59 to the main pump and distributing fan hereinafter described.

The train 11 of ells 12 as they are drawn from the supply reel 10 to the take up reel 22 rides along the horizontal platform 60, being appropriately confined therein by suitable side rails indicated at 61 and portions of the or enclosure which may be used to confine the cells within the unit.

The platform 60 is recessed longitudinally at 62 at a section of the platform 60 overlying the motor 51. The motor 51 is connected by a suitable gear reduction train which may be enclosed in the housing of the motor 51 to a drive shaft 64 carrying at its upper end the horizontal disk 65. Horizontal disk 65 carries the drive pins 66 extending normal thereto, the drive pins 66 being so arranged that when the motor 51 is operated, either of the drive pins 66 on clockwise rotation of the disk 65 will enter into the space between two adjacent cells 12, 12 in the area as shown in Figure l, and engage the lower surface of the trailing end of the forward cell of the two cells between which it enters and push that cell and hence the entire trail 11 towards the right with respect to Figure 1 continuously until on rotation of the disk 65 the pin 66 will move towards the right hand side of the disk 65 and extend from between the two cells.

It will be obvious that while disk 65 is here shown, a pair of arms may be used instead. Also it will be obvious that while two opposite pins 66 are here shown, a single pin 66 parallel to but remote from the center of shaft 64 will operate for the same purpose.

In the embodiment shown, however, the motor 51 and the sequence selecting circuit for motor 51 will be energized in response to the signal which is received to rotate the disk 65 through 180 so that only one of the pins 66 will perform the task of moving the train 11 by an appropriate step while the other pin 66 will be pre pared for such operation. It will also be obvious that where one pin 66 is used, the operation of the motor will be performed through a full 360 angle. Each operation of the motor 51 to move the train 11 will, in the embodiment shown, move the train 11 by a distance equal to two of the cellslZ; two cells will thus be moved into registry with the connecting apparatus 53 at a time and these two cells will be removed simultaneously to be replaced by another two cells at a time.

The connecting device 53 appears at the central portion of Figure 1 and is shown in greater detail in Figures 2 and 3. The platform '60 is either recessed or provided with a pair of openings at its point of registry with the connecting device 53 so that the two needle-like connectors may enter the cells in the manner described particularly in connection with Figures 2 and 3.

As abo've pointed out, two cells will, in the present device, be connected at one time although it will be obvious that the'device may be operated in such a manner that only one cell'need be connected at a time. The connectors comprise, as seen in Figures 1, 2 and 3, needle-like tubes 70, each of which is carried by a frame member '71 secured to an extension 72 of the armature 73 of an electromagnet 74. Energizationrof the magnet 74 by energization of lead 52 pursuant to operation of the sequence selector 48 in turn pursuant to the receipt of a s'ignalby the signal-responsive device 46 will cause the armature 73 to rise from the position shown in Figure 2 to the elevated position shown in Figure 3 where the needle-like connectors constituting small tubes with a sharp end will enter into the cells 12 which have been moved to a position of registry therewith.

The cells 12 comprise hollow containers which (see Figures 2 and 3) are provided with openings 80 at the bottom, which openings may be spaced from the platform 60 by so constructing the cells 12 that they are provided with longitudinal runners 81 at the bottom thereof. The openings 80 are scaled by a resealable membrane 82 of the so-called puncture proof or puncture sealing type so that after the needle tube 70 enters, as seen in Figure 3, and is thereafter withdrawn, the membranes 82 will automatically reseal to close the opening. If required, however, appropriate valve mechanism such as that shown in my above mentioned application at Figure 11 thereof may be utilized for closing the opening 80.

The needle like like tubes 70 are connected by the flexible hoses 85, 85 to the respective horizontal spray nozzles 86, 86 of the individual mixing chambers 87, 88 as seen in Figure 1. These horizontal spray nozzles 86 are more clearly seen in the detail of Figure 4 where they comprise part of a venturi-type spray assembly 90 consisting of a horizontal nozzle 86 and the vertical nozzle 91.

A bracket member 92 is provided adjustably positioned by a screw 93 in slot 94 on the base 95 of the mixing chambers 87 and 88. The bracket 92 is provided with an extension 96 entering the opening 97, 97 at the bottom of each of the chambers 87, 88 to which is secured a releasable mounting 98 for the vertical tube 91. The vertical tube 91 is connected by an appropriate hose 100 to the diaphragm pump 58 only one of which is shown in Figure 1 although it will be clear that a separate diaphragm pump 58 may be used for each of the vertical tubes 91 of the venturi-assembly 90 in each of the mixers 87 and 88. 1

Similarly, the horizontal tube 86 is secured by the adjustable mounting 1 on the extension 102 of bracket 92. The two adjustable mounting members 101 and 98 permit an adjustment of the nozzles 86 and 91 with respect to each other. The outer ends 103 of vertical tube 91 and 104 of horizontal tube 86 are shaped to permit secure attachment of the respective hoses 85 and 100. Thus when an appropriate signal is received by the signal responsive device 46, then the train 11 of containers 12 is moved to a position where the next two containers overlie the needle-like tube 70.

When this position of the containers 12 is reached, the pin 66 disengages the containers 12 which it has engaged owing to the completion of rotation of disk 65 through its angular movement and then the unit 53 is operated to raise the needle-like tubes 70 from the position of Figure 2 to the position of Figure 3 where they Will enter the cells 12. At this time, the blowers 55 and 56 and the diaphragm pump 58 are turned on.

The function of the diaphragm pump 58'which pump corresponds generally to the pump shown in Figure 7 of my prior application, is to generate an air stream through-tube 91 past the opening of tube 86, so that a lowering of pressure will occur at the mouth of tube 86 causing gas to be extracted from the cells 12. At this time also, an appropriate motor in housing 105'is turned onto operate the blowers 55 and 56 which drive a blast of air up through the conduits106, 106. Conduits 106, 106 are connected to the openings 97, 97in the floor of each of the mixers 87 and 88. A stream of air is thus driven up past the venturi member 90, thereby mixing the air with the perfume which has been drawn off from the smells and driving this perfume-air mixture into the manifold 110.

a At the same time, the main pump 111 and the distributing fans 112 are operated. The main pump is here shown in mere diagram form. Actually, the main pump is a large size pump operated by a motor of several horse power and connected by an appropriately large manifold to the conduit 110. This connection is merely indicated by the schematic line 115 between the manifold and the main pump. The output of the main pump is connected by individual conduits indicated by the schematic lines 116, 116 to the distributing fans, these conduits 116 being connected to the distributing fans in the manner shown I in Figure 5.

It is again emphasized that the connection is merely schematically indicated. This connection, however, is sufficiently large in cross-section to provide a full relatively frictionless flow of air from the manifold 110 to the main pump 111. Similarly the outlet conduits 116 from the main pump 111 to the distributing fans 112 are of sufficient size as to permit relatively unimpeded fiow of the volume of air mixed with perfume which it is desired to emit.

The individual fans 112 are placed in banks at appropriate locations in the viewing area so that an even distribution of the odor throughout the viewing location may be obtained.

Variousiother means may be utilized in connection with my novel device. Thus, should the perfume be contained in some kind of carrier which must be rapidly dissolved, I may provide in the lower sections of each of the pipes 186, a venturi-type member having a sturcture like that of the member 98, the horizontal nozzle of which will be connected to a container of solvent such as alcohol and the vertical nozzle of which will be connected to another diaphragm pump. Also, if it will enhance the rapid diffusion and perception of the perfume, I may provide heating coils at the lower ends of the pipes 106 to warm the air which is mixed with the perfume in the mixing chambers 87 and 88.

As pointed out in my prior application above men-' tioned, a relatively forceful smell such as the smell of an entire flower shop may be followed by a relatively mild smell such as the smell of violets. In such case it may be necessary or desirable if the smells immediately succeed each other to neutralize the forceful smell and for this purpose a pair of containers 12 in the series located between the pair of containers carrying the forceful smell and the following pair of containers carrying the light smell may be provided with an appropriate neutralizer or deodorant which will have the effect of immediately wiping out the forceful smell before the light smell is emitted.

In this case, the neutralizer or deodorant will be operated on and ejected by the device as if it were a perfume. Actually, however, by processing the perfumes so that they do not have a carrier or stabilizer, they will be extremely evanescent when removed from the containers and such neutralizer or deodrant will in that case prove to be unnecessary.

In Figure 5 I have shown a method of connection of the output conduits 116 at the individual distributing fans 112 so that the now perfumed air may be directed at the center of the fan and be automatically splashed out into the fan blades. For this purpose, the connector as shown in the upper right hand portion of Figures l and 5 comprise a block 120 having an opening 121 directed towards a plate 122 mounted at the center of rotation of the blades of fan 112. The opening 121 communicates with a smaller threaded opening 121a into which the mounting screws 123 carried by plate 122 may be passed, the block 120 being locked in position by the lock nut 124.

A lateral nozzle 125 carried by the block 120 and preferably integral therewith communicates with the main opening 121. Thus, the perfumed air from conduit 116 enters the nozzle 125 into the opening 121 and is directed against the splash plate 122. The perfumed air striking the plate 122 splashes out radially of the plate into the path of the air stream through the fan blades and is thus forced out into the viewing area.

By this means, therefore, a simplified device is provided for selecting perfumes in desired sequence with visual indicia and utilizing the visual indicia to establish at least the timing of the sequence.

A motion picture may be made having a plurality of scenes which may be accompanied by odors. The train 11 of cells 12 is then connected up with successive cells or successive pairs of cells having appropriate perfumes therein in a sequence matching the sequence of scenes on the film in connection with which the odors are to be emitted. Appropriate signals on the film may then be utilized to initiate a single odor emitting operation, the movement of the cells, the connection of the cells with the odor projecting apparatus, the operation of the odor projecting apparatus and the cessation of operation of the odor projecting apparatus, leaving the device ready for the next visual signal.

Also it will be obvious that various details of operation will enhance the capacity of my novel device to perform its function. Thus the diaphragm pump 58 and pumps 55, 56 may be shut off first with the main pump 111 and the fans 112 shut off slightly later to permit full clearing out of a particular odor from. the system before the initiation of the operation with respect to the next odor.

' It is intended by my novel device as presently constituted that all of the pump elements be at rest while no odor is being emitted. On receipt of the appropriate signal and connection of the needle like member 70 with the cells, pumps 55, 56 and 58 will go on, immediately followed by the energization of the main pump 111 and the fans 112. At the cessation of the odor emission cycle, pumps 55, 56 and 58 will go off first while at the same time the needle-like members 70 are disconnected from the cells 12 and the main pump 111 and fans 112 will go off a sufiicient time later (two or three seconds) to permit the cleaning out of odors from the system so that the system will be prepared for the emission of another odor.

Since the cycle ofthe unit will be preset as to time, each odor will be emitted for a particular length of time-say seven seconds. The perfume or odor itself may be prepared so that it will persist for a desired number of seconds beyond its original emission, although it has been found by experiment that the seven second emission of odor will create a psychological effect of a continuing odor as long as the scene persists. However, ifthe scene in connection with which the odor is, emitted lasts an appreciable length of timesay beyond one minute.then the apparatus may be signalled to recycle and the film and the train of cells may be prepared so that during the continuance of that same scene, an additional signal may be received to move the next pair of cells into place and this next pair of cells will have the same odor as the preceding pair.

Ordinarily it is expected that from twelve to twenty different odors may be used in connection with a single feature length film for particular scenes or sequences in connection with which emission of an odor may be appropriate, and that between such sequences no odor will be emitted so that a device of the type of my present invention in which forty-six cells may be wound in a spiral train on the supply drum or reel will ordinarily be sufficient.

Other arrangements including provision for changing of reels or drums of odor cells at the same time as the film reels are changed may be made. As a practical matter, in the use of my device it is preferred that the odor emission occur relatively occasionally of the order of say, twenty times in a feature length film, so that the audience will be, aware of the odor emission, being made so aware by the relatively greater length of time that no. odor is emitted. This willcompare with known methods of press entation of visual phenomena where in the presentation of motion pictures with sound, it is, known that accomrpanying sounds or accompanying music should not be emitted at a continuous volume but rather that the vol: ume. and quality of the sound as well as the type of music rises, falls and changes in accordance with the action,.the volume of sound becoming greater when certain phases of the action'are to be emphasized and falling away when the visual elements can carry on on their own.

In the operation of my novel odor emitting apparatus, the keying of the type of odors and the quantity of odors emission, to the particular scene is itself an art. Certain scenes which Carry a relatively tremendous visual impact requiring relatively little sound and relatively little odor, other scenes carrying relatively strong aural im act requiring relatively little visual action and relatively little odor emission, and still other scenes which. have been keyed down with respect to their visual action and aural impact being carried, maintained and impressed on theviewer by the emission of the appropriate perfume.

My present device permits the appropriate selection by the film editor or producer of appropriate perfume sequences suited to the action in the same manner that.

background music is similarly selected for aural satisfaction.

In the foregoing, I have described a preferred embodiment of my invention. However, it will now be obvious that many variations and modifications may be made by those. skilled in the art and I therefore prefer to be limited not by the specific disclosure herein but only by the. appended claims.
